River lifting fast on the rain. Take your time — read the water before you cast.

The water's still cold, around 8°C, it's just starting to lift, still carrying a fair bit of colour.

What would change the calculation
Warmer water — toward the 10–18 °C ideal band — would lift the temperature score.
The dawn and dusk windows score higher than the midday lull.

How to fish it · for rainbow trout
When
Nymphing can work through most of the day.
Where
Cover mixed depths.
Method
Start with tight-line nymphs and adjust if fish rise or drift higher.
Kit
9 ft #4 rod, floating line, 12 ft tapered leader to 4–5 lb fluoro tippet.
Why this works
Fair — barometric pressure is working for you, but insect activity is the limiting factor today.

About this water

The Mohaka is Hawke's Bay's great back-country river — a long, wild freestone cutting through gorge country off the Kaweka and Kaimanawa ranges, holding both brown and rainbow trout. The accessible reaches give good sight- and searching-fishing; the remote middle gorge is wilderness water reached by foot, raft or jet boat and rewards effort with uncrowded fishing. Read the level: it colours after mountain rain and is at its best falling and clearing.

Under the surface

The Mohaka cuts a long gorge out of the Kaweka and Kaimanawa ranges to the Hawke's Bay coast, a big, wild back-country river of greywacke and white water, much of it reached only on foot, by raft or by jet. Brown and rainbow trout hold in its boulder runs and green pools, in country that feels a long way from anywhere.

Wading: Remote gorge, big water, rapid rises after rain — back country care
